- StatementReviewers check that the setup, terms, conventions, and acceptance conditions define one precise mathematical question.
- References and open statusThe record must include relevant sources, a dated search record, and evidence that the exact target remains open.
- Parameterized instancesA fixed instance needs documented mathematical significance and an exact status check. Maintained sum-of-three-cubes and Busy Beaver frontiers qualify. Generated parameter sweeps require separate support for every record.
- Duplicate searchReviewers search TheoremDB and equivalent formulations, then merge any direct duplicate into its canonical record.
- Hero presentationContributors may supply a problem-specific teaching image or visual brief. Skipping it keeps qualification moving, and the page uses the labelled grey Mandelbrot placeholder. Supplied art must depict the mathematical object, use accurate alt text and a neutral caption, and record its rights basis.
Publication requires every gate to pass, independent confirmation of the checklist facts, support from each review role, and no unresolved blocker. Unknown or conflicting facts require staff review.
